Los Angeles -LRB- CNN -RRB- -- Former NFL star Darren Sharper , wanted in New Orleans in connection with the alleged rapes of two women , has turned himself in to Los Angeles authorities .

A source told CNN that Sharper made arrangements to surrender to Los Angeles police and did so without incident Thursday evening .

Los Angeles police confirmed the arrest but did not provide details .

Earlier Thursday , the Orleans Parish district attorney 's office in Louisiana had said Sharper , 38 , and Erik Nunez , 26 , each face two counts of aggravated rape .

If convicted , the two men face a possible sentence of life in prison without parole .

The New Orleans charges are in addition to charges Sharper already faces in California .

Nunez turned himself in to the Orleans Parish district attorney 's office shortly after 9 a.m. Friday .

Last week , Sharper pleaded not guilty to the California charges , which included two counts of rape by use of drugs .

CNN reached out to an attorney for Sharper and to Nunez Thursday , but neither returned messages seeking comment .

Prosecutors in Louisiana said the two alleged rapes occurred on September 23 in a New Orleans apartment .

The alleged rapes in California occurred in October and last month , authorities said .

Prosecutors there said the five-time Pro Bowl player , who became an NFL Network analyst , is also under investigation in Arizona and Nevada .

Police in Tempe , Arizona , say they expect to file charges against Sharper soon .

`` We have nothing yet . We anticipate filing charges very shortly and we are still waiting on a couple of results from the crime lab , '' Sgt. Mike Pooley said Thursday .

Las Vegas police said Friday that `` an active and ongoing investigation surrounding Darren Sharper '' was being conducted by the department 's sexual assault unit . Police provided no other details .

In addition , a Florida woman last month filed a sexual battery complaint in Miami Beach against Sharper relating to a 2012 incident , a police report said .

According to the report , the woman was with two friends at a Miami Beach club in September or October 2012 when she met Sharper . The woman , her friends and another person went to Sharper 's condo , where the woman claims the battery took place .

Miami Beach police are investigating the case , Miami Beach Detective Vivian Hernandez said last week .

One of Sharper 's lawyers disputed all the rape allegations last week at his hearing .

`` It was all consensual contact with women who wanted to be in his company , '' Leonard Levine said .

Sharper played for the Green Bay Packers , Minnesota Vikings and New Orleans Saints from 1997 through the 2010 season .

CNN 's Paul Vercammen reported from Los Angeles , and Saeed Ahmed wrote from Atlanta . CNN 's Steve Almasy , Dave Alsup , Suzanne Presto and Michael Martinez contributed to this report .
